U.S. national parks are beautiful to begin with. But when the deciduous trees that blanket so many national parks become aglow with radiant fall foliage, the spectacle is astounding. You might need to pack a sweater, but you can snap gorgeous photos, partake in special activities, and, of course, enjoy the colors of autumn when you plan a trip this season.
Although fall means fewer crowds (and perhaps the chance to more easily spot wildlife) in popular parks, the weather can be unpredictable, and some facilities even close up after the summer season. Be sure to contact your park for details on what's open and what's not before planning your trip.
